I was trying to turn off "User Interaction Enabled" in a UIImageView. I happened to be on the third tab of the settings for the object. I saw the "User Interaction Enabled" checkbox (near the bottom of the first screenshot), but unchecking it didn't work. What I didn't notice was that the header for that section of settings is "Accessibility". I finally found that the (identically named) setting I wanted is actually under the fourth tab near the bottom (see second screenshot). Tricksy.

 

When traveling from San Francisco proper to SFO on Bart, you can save 50 cents if you have the Bart-enabled Muni monthly pass. The trip I'm on right now--from Powell station to SFO--normally costs $8.10. But if instead of taking an SFO train from Powell, you take a Daly City train to Balboa Park (free with your pass because it's within San Francisco), and then switch to the SFO train, it only costs $7.60.

Note that as long as you do this only if the Daly City train is coming before the SFO train, it doesn't increase your commute time. When you get to Balboa Park, check the displays for when the next SFO train is coming. I like to make sure I have at least two minutes to get upstairs, exit the turnstile, reenter the turnstile, and then get back downstairs to the trains.

If for some reason you don't think you can make it, just get off the Daly City train and wait for the SFO one. You won't save the 50 cents, but at least you won't miss your flight.

Leslie Valiant, newly announced winner of the 2010 Turing Award, recently wrote a book called Circuits of the Mind. I headed over to Amazon to see what people have said about his new book. The one "review" that's there is really just some content lifted from Valiant's book, with no actual opinions expressed. This was curious, though, since the review's author is listed as a "Top 1000 Reviewer". I clicked to see his other reviews. He's written a ton, but all of them (or at least the first two pages of them) follow the same basic format:

5 stars

<A sentence or so of bio>

Here are some quotations from the book:

<one or more quotations from the book>

Clearly these aren't helpful as reviews, but it seems their creator has probably invested a decent amount of time making these. There's got to be an angle here, but I don't know what it is.
